Well, no instructions, no work to do.
Answer:
0.00012
Step-by-step explanation
because 0.3x0.4=0.12 and 0.12x1/10=0.012 and 0.012x1/100=0.00012
Let
x---------> <span>the width of the gravel path
we know that
72=(2x+6)*(2x+7)----> 72=4x</span>²+14x+12x+42-------> 4x²+26x-30=0
using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
x=1
the answer is
the width of the gravel path is 1 ft
Answer:
a) 32, 52
b) 18n
Step-by-step explanation:
a)
12+20=32
20+32=52
b)
4th element = 3n+4n=7n
5th element = 4n+7n=11n
6th element = 7n+11n=18n
Answer:
The answer is below
Step-by-step explanation:
The size of each box in the grid is 1 unit by 1 unit.
From the image, we can see that the size of the base of the square pyramid is 4 units by 4 units, hence:
Area of the base = 4 units * 4 units = 16 unit²
Also, as shown in the image, all the triangular face of the square pyramid are of the same size. the distance from the middle of the triangle base to the top of the vertex of the triangle is considered to be the height of the triangle. Hence, the height of each triangular face = 2 units
